Objective: The research aimed to investigate the effect of silicon foliar spraying in increasing drought tolerance in Camelina.Methods: The experiment was conducted as a factorial based on a randomized complete blocks design with three replications in a pot experiment. The treatments included two Camelina genotypes (Sohail cultivar and line-84), drought treatments (at two levels: without and with drought stress) and foliar spraying of sodium silicate (at five levels: 0, 2, 4, 6 and 8 mM).Results: The results showed that drought stress decreased grain yield, yield components, and morphological traits of both Camelina genotypes. Drought stress reduced the grain weight per plant of the Sohail cultivar and Line-84 by about 27 and 39%, respectively. Foliar application of silicon effectively increased yield and yield components. On average, foliar spraying of 6 mM silicon compared to the control treatment caused an increase in the traits of grain weight per plant (13.04%), harvest index (12.1%), and the number of siliques per plant (7%). In the correlation analysis, it was found that among the grain yield components, the highest positive correlation coefficient with the grain weight per plant belonged to the number of siliques per plant (0.941).Conclusion: Overall, it seems that foliar application of 6 mM silicon can be effective in increasing drought tolerance in Camelina.

In order to evaluate the yield components, seed yield, and oil content of Camelina doubled haploid lines, an experiment has been conducted based on a randomized complete block design with 40 doubled haploid lines (as treatments) and three replications in the research farm of College of Aburaihan- the University of Tehran, Pakdasht during 2020. Since the yield characteristics and oil content of Camelina lines are unknown in the Iranian climate, the study investigates seed yield components, as well as oil yield and oil content of 40 Camelina lines. The results show a very significant difference between Camelina lines in terms of yield components, which ultimately leads to significant differences in grain yield, thus affecting the grain oil yield. Although none of the lines has had absolute superiority in all components of grain yield, in terms of final grain yield, line of 134 with 3178 and line of 110 with 3120 kg/ha are identified as superior lines. Therefore, according to the purpose of this study, in order to select the best Camelina line with maximum grain and oil yield, 134 and 110 lines are introduced and recommended as superior and promising lines that are compatible with the climatic conditions of the Pakdasht region.
